A former personal assistant accused of defrauding Charles Saatchi and his ex-wife Nigella Lawson has told a court that she regularly found white powder and rolled-up bank notes in the TV chef's handbag.

Francesca Grillo told Isleworth Crown Court, in west London, she also found evidence of cannabis being smoked in the couple's house.
